$"video.{streamInfo.Container}" this seems to be the save location

yeah, I think I've just solved it

oh

It doesn't appear to have downloaded anything

That async void could be breaking stuff

Should be async Task

And it should then be awaited wherever you call it

Have ammended to this

but still seems to be not working

How do you call this download method?

just on a button click

Ah, it's some Winforms or something?

Uh, then you need dispatchers or some other funny stuff like that to call async code properly

Sorry, not my forte

No problem

you can use YoutubeExplode.Converter to download without needing to get the manifest
you juste need ffmpeg

is the accord video one the one I'd want?
